Abstract
A regenerative and friction brake blend control method for use in a vehicle with at least one positionable hydraulic brake actuator for achieving friction braking and an electric propulsion motor with regenerative braking capability wherein an amount of regenerative braking achieved is indicated by a signal, wherein the method comprises the steps of determining a hydraulic actuator position command indicating a desired vehicle braking, determining responsive the hydraulic actuator position command a regenerative braking command, commanding the electric propulsion motor to regeneratively brake the vehicle responsive to the regenerative braking command, receiving the signal indicative of regenerative braking achieved, converting the signal indicative of regenerative braking achieved to an actuator position reduction signal, subtracting the actuator position reduction signal from the hydraulic actuator position command to determine a difference command, and commanding the hydraulic actuator according to the difference command, wherein the hydraulic actuator and the regenerative braking together achieve the desired vehicle braking.
